In particular, by directly obtaining data about a tooth, dental (Dental) can minimize the effects of errors accumulated in each manufacturing process. The present invention relates to a method and apparatus for manufacturing artificial teeth using CT.

일반적인 인공치아 제조방법은, 도 1에 도시된 바와 같이, 손상된 치아의 표면을 삭제하는 단계와; 삭제된 치아의 표면에 인상재(印象材)를 도포한 후 경화시켜 인상채득(印象採得)한 음형인기(陰形印器)를 형성하는 단계와; 상기 인상채득한 음형인기에 석고나 금속 등을 주입하여 치아모형을 제조하는 단계와; 촉침식 스캐너 또는 레이저 스캐너를 이용하여 치아모형을 스캔하여 치아모형의 표면 좌표을 얻는 단계와; 스캔에 의해 얻어진 치아모형의 표면 좌표를 CAD/CAM 데이터로 변환하는 단계와; 변환된 데이터를 이용하여 3차원 N/C 가공기로 금속을 가공하여 인공치아를 제작하는 단계와; 가공된 인공치아를 일정 시간 동안 소결한 후 표면에 세라믹을 부착하는 단계;를 포함하여 이루어진다.A general artificial tooth manufacturing method, as shown in Figure 1, the step of deleting the surface of the damaged tooth; Applying an impression material on the surface of the removed tooth and curing the impression material to form an impression-accepted popular image; Preparing a dental model by injecting gypsum or metal into the impression-popularity; Scanning the dental model using a stylus scanner or a laser scanner to obtain surface coordinates of the dental model; Converting the surface coordinates of the dental model obtained by the scan into CAD / CAM data; Manufacturing an artificial tooth by machining a metal with a three-dimensional N / C processor using the converted data; And sintering the processed artificial tooth for a predetermined time and attaching a ceramic to the surface.

상기와 같이 구성된 인공치아 제조방법에 의하면, 손상된 치아에 덧씌워지는 인공치아를 3차원 N/C 가공기를 이용하여 제조함으로써 인체의 치열 구조에 맞게 치아를 제조할 수가 있다. 이하, 종래의 방법에 의해 인공치아를 제조하는 과정을 설명한다.According to the artificial tooth manufacturing method configured as described above, it is possible to manufacture the tooth according to the dental structure of the human body by manufacturing the artificial tooth which is overlaid on the damaged tooth using a three-dimensional N / C processing machine. Hereinafter, a process of manufacturing an artificial tooth by a conventional method will be described.

먼저, 치과에서는 손상된 치아의 신경 등을 치료한 후 그 표면을 삭제하고, 삭제된 치아의 표면에 인상재(印象材)를 도포한다. 이후, 인상재가 경화되면 치아로부터 이를 분리하여 인상채득한 음형인기(陰形印器)를 얻게 된다. 이 인상채득한 음형인기는 인공치아를 제작하는 기공소로 제공되며, 기공소에서는 이 인상채득한 음형인기에 석고 나 금속 등을 주입한 뒤 경화시켜 연마된 치아와 동일한 형상의 치아모형을 제조한다.First, in the dentist, after treating the nerve of the damaged tooth and the like, the surface is deleted, and an impression material is applied to the surface of the deleted tooth. After that, when the impression material is hardened, it is separated from the tooth and obtains the impression-popularity (陰 形 印 器). This impression-acquired negative popularity is provided as a laboratory for manufacturing artificial teeth, and the laboratory produces a tooth model having the same shape as the polished tooth by injecting and hardening gypsum or metal into the impression-acquired negative popularity.

이와 같이 치아모형을 제조한 후에 촉침식 스캐너 또는 레이저 스캐너를 이용하여 치아모형을 스캔하게 되는데, 이 스캔 작업을 통해 치아모형의 표면에 대한 좌표를 얻을 수 있다. 이어서, 스캔에 의해 얻어진 치아모형의 표면 좌표를 CAD/CAM 데이터로 변환한 후, 이 데이터를 이용하여 3차원 N/C 가공기로 금속을 가공하여 인공치아를 제작한다.After the tooth model is manufactured, the tooth model is scanned using a stylus scanner or a laser scanner. Through this scanning operation, the coordinates of the surface of the tooth model can be obtained. Subsequently, after converting the surface coordinates of the dental model obtained by the scan into CAD / CAM data, a metal is processed with a three-dimensional N / C processing machine to produce artificial teeth using this data.

인공치아의 제작이 완료되면, 가공된 인공치아를 일정 시간 동안 소결한 후 표면에 세라믹을 부착하여, 실제 치아와 유사하게 변화시킨다. 이후, 이 인공치아는 치과로 옮겨져서 환자의 치아에 본드 등으로 부착되어 치과 치료가 완료된다.When the manufacture of the artificial tooth is completed, the processed artificial tooth is sintered for a predetermined time, and then a ceramic is attached to the surface, thereby changing it to be similar to the actual tooth. Thereafter, the artificial tooth is transferred to the dentist and attached to the patient's teeth by a bond or the like to complete the dental treatment.

그러나, 상기한 종래의 인공치아 제조방법은, 그 제조과정이 복잡하여 제조비용이 증가하고 생산성이 저하되며, 인공치아의 제조과정에서 환자의 치아에 정확하게 일치되는지 확인하기 위하여 환자가 병원을 여러 차례 방문해야 하기 때문에, 환자가 불편함을 느끼게 되는 문제점이 있다.However, in the conventional artificial tooth manufacturing method, the manufacturing process is complicated, the manufacturing cost increases, productivity is lowered, and the patient visits the hospital several times in order to check whether the artificial teeth are exactly matched to the patient's teeth. Since there is a need to visit, there is a problem that the patient feels uncomfortable.

또한, 인상채득한 음형인기(陰形印器)를 제작한 후 이를 이용하여 치아모형을 제작하고 이 치아모형을 스캔하여 금속이나 세라믹 등의 인공치아 재료를 가공하게 되므로, 각 제작단계에서 에러가 누적되고, 이 누적에러로 인하여 실제 치아의 형상과 인공치아의 내부 형상이 달라져 치아에 정확하게 부착되지 않는 문제점이 있다.In addition, after making an impression-acquired sonic popular shape, a tooth model is used and an artificial tooth material such as metal or ceramic is processed by scanning the tooth model. Accumulated, due to this cumulative error is the shape of the actual tooth and the internal shape of the artificial tooth is different, there is a problem that does not adhere correctly to the tooth.

특히, 여러 개의 치아가 연결된 브리지(Bridge) 형상의 인공치아를 제작하는 경우에는 3차원 변형이 발생하고, 브리지의 길이가 길 경우에는 변형이 심해져 치아에 정확하게 부착되지 않아 별도의 고정작업이 요구되는 문제점이 있다.In particular, in the case of manufacturing a bridge-shaped artificial tooth in which several teeth are connected, three-dimensional deformation occurs, and when the length of the bridge is long, the deformation is severe and it is not attached to the teeth precisely so that a separate fixing work is required. There is a problem.
